With just two days before the second leg of the Triple Crown, Kentucky Derby 140 Champion California Chrome's health came under question Thursday, after the horse was heard coughing after a galloping routine.

In all six of his wins this year, California Chrome wore a nasal strip. The manufacturer said the strips can improve performance and decrease the chance of bleeding in the lungs in race horses.

In the past, the New York Racing Commission has ruled against horses wearing those strips.

On Monday morning, the three Stewards at Belmont Park unanimously agreed to allow the use of equine nasal strips for all horses running at racetracks of The New York Racing Association, Inc., effective immediately.

"Equine nasal strips do not enhance equine performance nor do they pose a risk to equine health or safety and as such do not need to be regulated," said New York State Gaming Commission Equine Medical Director Dr. Scott Palmer, who gave the Stewards an expert analysis recommending the ban be discontinued.

After his Preakness Stakes win this weekend, California Chrome's trainer Art Sherman said the horse's co-owner might not run the horse if he couldn't wear the nasal strip.

The Belmont Stakes will be held June 7.

Of the 38 horses who have won the Derby and Preakness, only 11 have gone on to victory in the Belmont Stakes, the longest of the Triple Crown races.
